Magnesium Oxide

Technical Index

Application field：

It is the determination of sulfur and pyrite in coal and sulfur and arsenic in steel. Used as a standard for white pigments. Light magnesium oxide is mainly used as raw material for the preparation of ceramics, enamels, refractory crucible and refractory bricks. Also used as polishing agent adhesives, coatings, and paper fillers, neoprene and fluorine rubber accelerators and activators. After mixing with magnesium chloride and other solutions, magnesium oxide water can be prepared. It is used in medicine as an antacid and laxative for gastric acid excess and duodenal ulcer disease. Used in the chemical industry as a catalyst and raw material for the manufacture of magnesium salts. It is also used in the manufacture of glass, dyed meal, phenolic plastics, etc. Heavy magnesium oxide is used in the rice milling industry for firing milling and half rollers. Construction industry for the manufacture of artificial chemical floor artificial marble thermal insulation board sound insulation board plastic industry used as filler. It can also be used to produce other magnesium salts.

One of the main uses of magnesium oxide is the use of flame retardants, traditional flame retardant materials, widely used halogen-containing polymers or halogen-containing flame retardants combination of flame retardant mixture. However, once a fire occurs, due to thermal decomposition and combustion, it will produce a large amount of smoke and toxic corrosive gases, which will hinder fire fighting and personnel evacuation, corrosion of instruments and equipment. In particular, it has been found that more than 80% of the deaths in the fire are caused by the smoke and toxic gases produced by the material, so in addition to the flame retardant efficiency, low smoke and low toxicity are also essential indicators of flame retardants. The development of China's flame retardant industry is extremely unbalanced, and the proportion of chlorine flame retardants is relatively heavy, which is the first of all flame retardants, of which chlorinated paraffin occupies a monopoly position. However, chlorine flame retardants release toxic gases when they act, which is far from the non-toxic and efficient pursuit of modern life. Therefore, in order to comply with the development trend of low smoke, low toxicity and pollution-free flame retardants in the world, the development, production and application of magnesium oxide flame retardants are imperative.
